[Caml-list] Has anybody gotten delimcc to work?

[Michael C Vanier <mvanier@cms.caltech.edu>]

I've been trying to use the delimcc delimited continuation library, but 
so far I've been unsuccessful.  I'm using OCaml 4.06.1 and I've tried it 
on both Mac OS X (High Sierra) and Ubuntu MATE 17.10. I'm fine sticking 
to bytecode.  The opam package installs correctly but when you try to 
run it you get errors from the dynamically-linked libraries.  On Mac OS 
X I get this:

# #require "delimcc";;
Cannot load required shared library dlldelimcc.
Reason: /Users/mvanier/.opam/4.06.1/lib/stublibs/dlldelimcc.so: 
dlopen(/Users/mvanier/.opam/4.06.1/lib/stublibs/dlldelimcc.so, 10): 
Symbol not found: _alloc
   Referenced from: /Users/mvanier/.opam/4.06.1/lib/stublibs/dlldelimcc.so
   Expected in: flat namespace
  in /Users/mvanier/.opam/4.06.1/lib/stublibs/dlldelimcc.so.

And on Ubuntu I get this:

# #require "delimcc";;
/home/mvanier/.opam/4.06.1/lib/delimcc: added to search path
/home/mvanier/.opam/4.06.1/lib/delimcc/delimcc.cma: loaded
Cannot load required shared library dlldelimcc.
Reason: /Users/mvanier/.opam/4.06.1/lib/stublibs/dlldelimcc.so: 
dlopen(/Users/mvanier/.opam/4.06.1/lib/stublibs/dlldelimcc.so, 10): 
Symbol not found: initialize.

However, in either case I can do:

# open Delimcc;;

and it reports no errors, but then if I try e.g.:

# shift;;
Reference to undefined global `Delimcc`

so it appears the library isn't there or isn't functional. Compiling 
from the delimcc source also appears to work, but gcc warns about 
implicit declarations of "alloc", "alloc_shr" and "initialize" when 
compiling stacks.c, which makes sense.  Compiling any of the test 
programs also fails.

So it appears that this library no longer works.  Does anyone know any 
way to make it work?

Thanks in advance,

Mike
